MACHINE FOR SHAPING TUBULAR GLASS ARTICLES.

Specification of Letters Patent.

Patented May 27, 1919.

Application filed May 31, 1918. Serial No. 237,425.

To all whom it may concern:

lie it known that I, Bonner KOENI'G, a citizen of the United States, residing at Camden, in the county of Camden and State of New Jersey, have invented certain new and useful Improvements in Machines for Shapchine covered by my-United States Patent,

982,212, January '17, 1911, with the exception that the machine of my present invention is capable of doing a greater variety of worlc. One object of my invention is to provide a machine of the above mentioned type which is of simple construction and capable of imparting various shapes to glass tubes, bottles, or the like. L

Another object is to so construct my'improved machine that it will produce practically perfect work at a high rate of speed. A further object is to produce a durable machine: of the above described character which will require comparatively little power and which will turn out a large pro duction of properly finished articles.

These objects, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which Figure 1 is a front elevation of lay irriproved machine,

Fig. 2 is a top plan view of Fig. 1,

Fig. 3 is an elevation of the right hand end of my improved machine,

Fig. 4 is a transverse sectional elevation taken on the line 4-1 of Fig. 1,

Fig. 5 is a transvelse sectional elevation taken on the line 5-5 of Fig. 1,

Fig. (3 is a fragmentary transverse section of certain of the elements shown in Fig. 5, showing them moved/into an operative position.

Fig. 7 is a fragmentary elevation partly in section, showing tube holding and re leasing means which is mounted at the top of the machine and as partially shown at the topof Figs. 1 and at,

Fig. 8 is a fragmentary sectional elevation of the shaping means which forms a part of my invention, taken on the line 8-8 of Fig, 2, and showing certain of the parts in different positions which the occupy during the operation of the machlne,

Fig. 9 is a view of similar natureto Fig. 8, showing certain ofthe parts in othe'r'positions which they occupy during the operation of the machine, and

F'g. 10 is a transverse fragmentary section taken on the line 10 -10 of Fig. 8.

Referring tothe drawings, 12 represents a supporting base having two standards 13 and 14 secured thereto. These standards are spaced apart and at their tops form a support for a magazine 15"for containing glass articles to be shaped, in the present instance these articles being shown in the form of glass tubes 16. The magazine 15 ineludes two oppositely disposed channels 17 which are spaced apart.

A'detent plate 18 is hinged at its-top to a bracket 20 and at,its bottom is provided with a lip 21which is slightly curved upwardly,

as clearly shown in. Figs. 4 and 7 This lip 21 normally occu ies a position below the bottom tube 16 in he magazine 15 and thereby' normally supports all of the tubes in the magazine. The stationary bracket 20 includes a strip 22 ,in whichis secured a curved rod 23 having a nut 24 on its screw threaded outer end. This rod 23 is curved in an are concentric with the swing of the detent plate 18 and the detent plate 18 has a hole through which the rod freely passes.

18 while the other end of the spring abuts the nut 24. holds the detent plate in the position shown in Figs. 4 and 7. However, it will be noted that the detent plate 18 can be swun rearwardly against the action of the spring 25 andthis action occurs during the operation of the machine to permit the bottom tube to fall out of the magazine, the remaining tubes in the magazine being temporarily supported by auxiliary supporting means in a manner hereinafter described.

Thus the spring 25 normally A stationary cylindrical shaft 26 has its these posts form a bearing for two flangedrollers 29. These rollers are positioned.di rectly below the magazinelfr and a adept tubes 16 adopted to be SUCCOSviVBly dropped upon the rollers 29 upon the mega Zine by the operation of releasing means above mentioned and hereinafter more specifically described. The rollers, being rotated by the pulley and belt will rotote the glass tubes, and during; this rotating .ion, the enei portion oi the tube can be ilQ-itl/Sil by any suitable means, such "for exempl the gilt-J jets illustrated above m ntioned liltetes 982,212 of tube is pro i it will be op upon by meclmnisv new to be described r us 35 1111 i 3G, iii their lower ends are loosely mounted upon the stetionmsy shaft 26, The upper end 'I'ic erm has two fingers 3? and 3?) adj! tzibly secured. thereto, the outer ei'uls of sari fii'igcrs red apart and 'bfuzreeterl ou'forltecl mirl y shown in Fi a l (3.

After the tube 16 has been raised and While it is being held. by the fingers 37, 38, and 39, it is operated upon by a/ rot'ltable shaping tool 51;)tl1e axis of which is in alimemcnt with tlie zi'liis of the glass tube when in its raised position enclhelcl by said fingers. The standard 14 has a bushing 49 and. a cylindrical SlEGWG 50 is 'edeptcd to slide longitudinally and rotate Within said. bushing. The shaping tool 51 includes a plunger 52 having a central stem 53 and two spring ill'lllS conriecteiil thereto. The arms 54; are attached to the stem 53 and normally teml to soreod apart iue to the resilient action of tlic materiel comp ising the arms. The arms 5%: at i eir outer end. are pro vided With jaws l ming tapered surfaces 56 ud pte l o comet with an inwardly bevcical endw em on the sleeve so that ii the sleeve 1o. moved into engagement with the tapered surfmres 56 ofifthe jaws 55, it will reus sa d to be contracted or moved.

'lliesteizi bowl 538 u s e centering ing the opera. '0 be projected into the as? L6, in. a. manner here oni olei-iialy ale-scribed.

A SpTiKlfi. ,1, Wheel lit is mounted. so as to rotae on t. i bushing i9 and this 4., wiles-l list; a clutch collar secured. thereto and. including miuulerly disposed clutch teeth 61. The plunger 52 has a 'pin 62 which projects mitwzirdly through an elongated slot 63 in the sleeve 50. The slot 63 extends in the direction oi the length of the sleeve so that the pin 62 permits a reletive sliding movement between the tool 51 and the sleeve 50, sliding movement being su'fiicient to perm beveled end 57 to engage the tapered so. feces 5 5 of the jaws and thereby eeuee the la, 1 to e moved toward each other, as above clescr a;

The sprocket 59 is connected to another sprocketwhich is freely rotatable on the secondary shaft 26. Another sprocket secured to the sprocket 641 and a chain 66 operutiv'ely connects the sprocket 6:; with a Sprocket 67 the u'iain driving shaft. The sprocket (35 being of all. diameter compared to the sprocket 5 the sprocket 59 will be driven at a compm lively high speed.

The sleeve 230 is provided With a, heed 68 which is adopted to b e'ig god with e cam letter li in' ireely mounted on I he cam arm 69 "2'0 secured to spring serves o me we beeono to move engeqcmen with r/ the head 68 of the sleeve 50' when-permitted to do so by said cam 70. i A coiled spring 72 normal holds the sleeve 50 outwardly in the position clearly 5 shown in Figs. 1 and 2'. However, when the cam 70 is rotated, the spring 71 will pull the ram arm 49 so that'the latter will push the head 68 and the sleeve 50 inwardly and will consequently push the-tool 51 toward. the 1.0 heated end of the glass tube 16 while being held by the fingers 37, 38,.and 39.

. The first part of the'inwardmovement of the sleeve 50 willinerely be a sliding movelnent until the pin. 62 engages the clutch teeth 6 1 and since the clutch, rotates constantly it will carry the pin 62 with it and consequently rotate 'both the sleeve 50 and the tool 51. As soon as the pin-62 abuts. or engages 'the clutch teeth, it will be stopped 20 as far as inward movement is concerned. However, the cam arm 69 ontinues to push against the head 68 and n so doing causes the sleeve 50 to engage 'th pered surfaces 56 of'the tool 51 and thergiy ov'es the jaws 55"togetller. l w r TlllS action't'akes place after. the centering head 58 has entered the, heated glass tube so that the jaws 55,; when moved together,-

I tend to compress the heated portion,of;the'

so'glas's tube Aa'ndzsince the toolis rotating the tube will; be-shaped accordance with the shape'ot the interio of the jaws.

' These jaws, itgwill -be understood, can be ,varied in-shapeto causediiferent shapes to y .35 be formed upon the less. It will also be understood that, the s ot63permits the 1on gitudinal movement of the sleeve independentlyof the movement ofthe tool so' as tomove the jaws'together, as abovedeo scribed. 1,.

A stop bar 73 is'slidably mounted in the 1 top o fthe standard .13 and can be secured in,

various positions bya nut 74. The/stop-bar 73 is m alinement with the. tool451 and also V 45 in alinementwith fthevglass tubeslfi while they are held by. the fingers 37, 38, and 39.

and forms a stop-or'abutment' for the adjacent-ends of thetube's whilethe tool 51 is operating upon themito shape the ends.

. carries a dividing plate' 76 adapted to engage between the lowermost-tube inthe magaz ne 15 and the tube which is directly above it. This dividing plate'also serves,

- when moved towardthe last tubes by a spring 77, to engage the detent platev l8 and pushnt rearwardly so as to -free the;bo'ttom tube and permit the latter to drop upon the l Alever 75 (see 'jFig'. 4) -is mounted so asto be free to swing upon .the shaft 26 and a from the been shaped by the tool and the latter has moved away from the tube, permitting the" tnbeto rest upon said rollers.

A chute 80 is supported in an inclined.

position so that the finished tube, after hav- 111g been ejected by the arm 7 9, can roll into 1.

a receptacle (not illustrated) which can-be mounted at the lower portion of the 'chute."

It will be noted that when the lever is moved by the cam 78 that the dividing plate 75 76 will also be moved away from the tubes and permit them to drop downwardly upon the detent plate'18, the latter being moved, by the spring 25, into its normal position when permitted to do so by the retractiye 80' movement of the dividing plate 76,"

In the operation of my improved maehinej the dividing plate 76 divides the lowermost tube from the tube immediately above it in the.-'magazine and then moves the detent plate 18 from under the lowermost tube. The latter, then falls upon the rollers 29' which are constantly rotating and, therefore, the tube will receive a movement of rotation while resting upon these rollers. During this time the end portion of the tube nearest to the tool 51 Wlll be heated completely throughout its eircumierence and;

oy using burners such as illustrated in my former patent above mentioned, this heating 9.5 1 action being extremely rapid. 'When the tube becomes sufiiciently hot to'soften' -thej .glass so that it can be worked by the tool, the 1 fingers 37, 38, and 39 move into engagement} with the tube and raise it out of engagementfioo with the rollers and into direct alineme'nt with the axis ofthe tool. The tool .theu' moves, due to the action of the elements.v above described, toward the end of the tube until the jaws of the tube surround the soft-1,166

ened and heatedportion and the centering j head.pas's esiwithinthe tube. v The final" 'nward movement of the tool then 'eauses the jaws to move together while they are rotating and thus the heat-softened 1 portion of the tube is annularly shaped, oorresponding to theeharacter of the tool jaws I employed. Whilethe tool is operating upon 1 I the tube the latter is firmly held against r0 tation by the fing'ers' 37, 38, and 39 and after havingjcompleted its work the springr72 willmove the sleeve 50 ofthe tool outwardly to release the jaws from the glass tube and,

vthen will move the entire tool as a unit away 3 glass tube, permitting the latter 12 to drop againupon the rollers 29 when the fingers move apart.

The lever .75 then moves rearwardly so l that" the ejecting arm 79 pushesthe finished tube from the rollers upon the chute 80 and the dividing plate 76 a ain performs. its function of causing anot or tube to dropupon-said rollers. It will be noted that the cam- 78 is so designed. as clearly shown in r Fig. 4, as to permit the member 75 and mm:

namely, the spring 42 so that thereis no I claim as new and desire to secure ticle' a pluralit harsh gripping article within said recesses-1 l members then being operative toifirmly hold action which would injure the tube or which would not permit it to be slightly'moved in case of any irregularities in'the positioning of any of the elements if such shghtmovement were necessary. How-i ever, these tube-engaging fingers are capable of raising {the tube into practically perfect alinement with the tool.

While I have described my invention as taking a particular form it will be understool that the various parts of my invention may be changed without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider thatI am at liberty to make such changes and alterations asfairly come with mcludmg means-i0! rotatably supportmg in the scope of the appended claims.
